C. D. DALLAS S CALE PLATFORM 2 Smets-sheet 2 Patented Nov. 20, 1923.

To @YZ 'zu/tom t may concern Be it known that I, CHARLESk l). DALLAS, a citizen of the United States, residing at lllinnetka, in the county of Cook and State of illinois, have invented certain new and useful improvements in Scale Platforms, of whichA the following is a description.

My invention belongs to that general class of devices known as scale platforms or the 19 like, and relates to an auxiliary platform adapted' to be used in connection with a scale for supporting a crate, box orcarton in which articles may be packed, particularly during the packing as well as during the nailing up or fastening of the crate, but which will permit weighing the contents in the usual manner. More particularly it relates t a device for carrying the box or crate, whereby the crate need only be on the 2O scale platform during the weighing operation.

The invention has among its objects the production of a device of the kind described that is simple, convenient, eiiicient, compact, durable and satisfactory ifor use wherever found desirable.

Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art 0 from` the disclosures herein given.

To this end my invention consists in the novel construction, arrangement and conibination of parts herein shown and de scribed,l and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts,

Fig. l is a side elevation of my improved device in operative supporting position;

Fig. 2 is a sectional view taken substantiallyl on the line 2 2 of Fig. l;

Fig. 3 is a sectional view taken substantially on the line 3 3 of Fig. l.

Fig. 4 is a top plan view;

Fig. 5 is a sectional view taken substantially on the line 5-5 of Fig. l.

Referring to the drawings, in which the preferred embodiment of my invention is shown, l represents any usual type of scale and 2 is what is usually termed the scale platform, upon which the article to be weighed is placed. I have shown a box or crate 3, the contents of which it is desired to weigh, it being understood that the UNITED STATES PATENT OFFICE.v

SCALE PLATFORM.

Application filed l'lecember 31, 1921. Serial No. 526,278.

scale and box or crate may vary, this depending upon the particular installation of my device. As shown in Fig. l in the full lines, the box is supported above and entirely oif of the scales; in the dotted lines it is shown on the scale platform 2, in which position the weight may be taken In the construction illustrated, my device consists of a stationary frame or base and an adjustable frame carried thereby. The stationary or base frame as shown, consists of an end bar e provided with the rlp-turned portions 5, 5, Varranged at one end, and a similar U-shaped part 7, provided with up-turned ends 8, arranged at the other end, the two being connected by the side bars l0, it being understood that the parts may be secured together in any suitable manner. I also prefer to provide the side frame members 6, 6, and 9, 9, which may be secured to the parts 5y and 8, in any suitable manner. As most clearly shown in Fig. 3, there is also provided a supporting lmember consisting of the parts ll andl2 secured to the side bars l0, these being arranged substantially intermediate the' ends of the frame.

The movable or adjustable frame consists of the end bars la'- and 15, the parts being. suitably secured together 1n any desiredy manner, as by bars 13. As shown, the movable frame is connected to the base frame by the desired number of links i6 and i9, the links being preferably arranged in pairs and secured to the opposite sides of the bars 13 and l0 by bolts, rivets, or the like, 1T and 18 and 2O and 2l respectively. The links are of such length that when standing in the position shown in Fig. l the frame bars 13 will be high` enough to support the box or crate 3 entirely olf the scale, but when the frame is rorked for ward, as shown in the dotted lines in Fig. l, the frame may drop and place the box or crate on the scale platform 2. For convenience in operating, l have provided a handle 22 at each side of the frame and secured to the links as at 23, the two levers 22 being connected by a cross bar 24, if desired. Stop members may be pro-vided if desired, to limit the movement o-f the box on the frame, in one direction.

It will be noted, by referring to Fig. l, that when the frame is in its raised position the links are swungslightly past the center,

with the trame bars 13 resting on the npright 6, so that the weight represented by the crate or box 3 is rigidlj,T carried, but oli the scales. The saine may be packed while so supported, or while resting,` on the scales, It packed in its elevated position, the 'traine may be swung; as indicated in the dotted lines in Fig, l, so that the crate rests upon the scales while the movable traine rests upon and is supported by the 'upriglits ll and `iViren the crate er box is packed to the de sired extent it is elevated, shown in iull lines in Fig. l, and maj/.i then be nailed np, er otherwise secured. However, durinj nailing or securing oi the bon: and con c c, none ot the hammering, vibration or the like, is transmitted to the scales, thereby, throwingthem out ot adjustment, as might be the ease were the boi; nailed shut while restinoV on the scales. lt also will be noted that the box or crate may be substantially easily moved ntl et the support, and even though it drags on one side bar i3, yet, nevertheless, there is no dragging; on the scale, with the possibility ot throwing` the saine ont ot adjustment,

The device is exceedingly simple and in expensive, and in addition to saving the scales it has been found that the box may lie nailed up more securely or otherwise closed, owing` to the tact that it is rigidly supported.

,lolaving` thus described my inventimi1 it is obvious that varions immaterial modifican tions may be made in the same without deiartinfa 'from the spirit oli my invention; hence l do not wish to be understood as limitingg` myself to the exact torm, construction, arrangement and combination of parts herein shown and described or uses inentioned.

lllhat l claim as new and desire to secure by Letters Patent is:

l. In a scale attachment device ot the kind described and .in comliiination, a base constructed to receive a scale base, a load carrying trame, means for adjustably con meeting' said trame with said 'firstmentioned base 'whereby the same may be elevated or lowered as desired, means cooperating with said connectingr means to support the traine in its elevated or lowered position, as dei ,avancee aired, and a handle 'tor moving said traine as desired.

'ifhe combination with a scale. o a device otI the kind described, comprising a loadreceivingY 'traine adapted to be arran ed above the scale iiilatiforin and swingjlngily movable in a vertical plane relative thereto, ttor swinging said lfminie to raise the i o l scale platlorin or to lower it thereonto, and means :tor rigidlyvv holding; the trame in said tirst-ineiitioned position.

3. The combination with a scale, olf a dew vice ot the kind described, Aoinprising,v stationary -trame, a load-receiving fraaie movably connecter, thereto, and means 'ifor operating said lastanentioned Ytrame to nieve said load onto or oit' oit said se le, and means independent of' said lastancntioncd means i'or rio-idly snpportino' said load and movable 'traine oliI said ale,

4i. The combiiiatioii with a scae oli a de4 vice oi the kind descriliiil, coniilirisiiagr i stationary 'trame a movable load-rcceiving Yl'ranie thereabove, links swingingly connecting said iframes, means tor moving)` said load receiving trame relative to said stationary ilrain to swing said load onto or oil ot the scale, and means between said trames l'or rigidlysupporting said load-receiving Yframe at both the ends ot its pivotal movement.

5. The combination 'with a scale, o lf a devil-e ot the kind described,y compi-ising;v a stationary Yframe, a Ytraine superimposed thereon and surrounding` said scale plattorni, links swii rinnly connecting; said iti-:mics at the opposi e sides thertai'li.` means i'or swinging the uppermost Yli'rame l,elow said scale platform to release the load thereonto. and lor fitting` said load therealiove so as to lie tree thereof, and vmeans ifor su]ii'iortinc said loaded iipiiicrniost 'traine in its lastaiien tioned position, said means engaging; .said uppermost 'i'rame when said links li ve been swung; gast their vertical positions.

ln testimony whereof, l have hereunto signed my name in the presence ol" two sul scribing witnesses.
